T it U her below, although, if desired, this may he Be it known that I, \VILLIAM J. AUSTIN, a accomplished by providing holes through the citizen of the United States, residing at Milbase-flanges of the rails or between the rail waukee, county of Milwaukee, and State of ends. Such openings may easily be formed \Visconsin, have invented new and useful by breaking oft one corner of the base-flange Improvements in Rail-Joints, of which the of the rails, Fig. 5.
